Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166444, here are decompositions:

41 + 166403 = 166444
197 + 166247 = 166444
293 + 166151 = 166444
401 + 166043 = 166444
431 + 166013 = 166444
461 + 165983 = 166444
503 + 165941 = 166444
557 + 165887 = 166444

Showing the first eight; more decompositions exist.
